Customized long range COFDM video transmitter for camera surveillance
It’s a new powerful HD COFDM video transmitter, can up to 15-25W RF power which supports transmitting over a long distance. With the latest technologies of COFDM modulation and H.264 image compression that enables good NLOS (Non-line-of -sight) transmission with DVD quality video. The transmitter is compact size with a strong power amplifier for long range transmission. Good heat resistant with two cooling fans. Be safety with AES128 bits. Can work well in fast-moving transmission.
This military backpack man-portable transmitter is special for entering into the area of the incident to gather information and signal transmission under the condition of heavy obstacles, such as many building barriers, severe electromagnetic interference, remote mountain town or other harsh environments.
At the front-end personnel, scouts, firefighters, rescue personnel or television interview personnel using small size, backpack or Buckle format transmitter transmit the live signals to the rear command vehicle. Then the command vehicle will receive the image displayed on the monitor via the receiver which convenient for real time understanding of the site condition and timely command.
